NRCS Root WAD (Water Available for Diversion) is a critical measurement used in water resource management to determine the amount of water available for diversion from a water source. This calculator helps you compute Root WAD based on key parameters and provides examples to illustrate its practical application.
What is NRCS Root WAD?
The NRCS Root WAD is a concept used in water resource management to determine the amount of water available for diversion from a water source. It is calculated based on the water supply, demand, and other factors to ensure sustainable water use.
Understanding Root WAD is essential for water resource managers, farmers, and policymakers to make informed decisions about water allocation and usage.
How to Calculate Root WAD
Calculating Root WAD involves several steps and requires specific data inputs. The process typically includes:
- Determining the water supply available from the source.
- Assessing the water demand from various users.
- Considering environmental flow requirements.
- Applying the Root WAD formula to compute the available water for diversion.
Accurate calculation of Root WAD ensures that water resources are used efficiently and sustainably.
Root WAD Formula
The Root WAD is calculated using the following formula:
Root WAD Formula
Root WAD = (Water Supply - Environmental Flow) - Water Demand
Where:
- Water Supply is the total amount of water available from the source.
- Environmental Flow is the minimum amount of water required to maintain the ecological health of the water source.
- Water Demand is the total amount of water required by all users.
This formula helps in determining the amount of water available for diversion while ensuring that environmental and user needs are met.
Example Calculations
Let's look at an example to illustrate how to calculate Root WAD.
Example 1
Suppose the water supply is 10,000 acre-feet, the environmental flow requirement is 2,000 acre-feet, and the water demand is 5,000 acre-feet.
Using the formula:
Calculation
Root WAD = (10,000 - 2,000) - 5,000 = 3,000 acre-feet
In this example, the Root WAD is 3,000 acre-feet, which is the amount of water available for diversion.
Example 2
Consider another scenario where the water supply is 15,000 acre-feet, the environmental flow requirement is 3,000 acre-feet, and the water demand is 8,000 acre-feet.
Using the formula:
Calculation
Root WAD = (15,000 - 3,000) - 8,000 = 4,000 acre-feet
Here, the Root WAD is 4,000 acre-feet, indicating the available water for diversion in this scenario.
